i just ordered a razor lachesis from ebay, i choosed that bcs many ppl said that the material on the mouse is great, good for right and left handed ppls, and also has great tracking ability 4000dpi, i had one logitech laser it wasa bit big with 2000dpi, unfortunately broken, right now i am using mx500 old logitech, itsa bit big but it has nice shape, oh 1 cons to the razer- hasnt got weight adjustment, wich i think important, but anyway i bought it bcz that is the best gaming mouse on the earth right now, cost only 78 euros with shipping )
